Directed Discovery of Crystal Structures

Description

This contribution is modified from a published exercise "Directed Discovery of Crystal Structures Using Ball-and-Stick Models" [Mogk, 1997] . While the published exercise is based on student exploration of traditional ball-and-stick models of crystal structures, this modified version uses a similar "discovery-based" approach to teach the spatial relationships and crystal-chemical rules that govern the crystal structures of common minerals and crystalline solids, but instead uses the latest web-based crystallographic information and visualization programs. A few changes in the content have been made from the published exercise, mainly to accomodate the new digital media.
